The upper end of the handle is fixedly installed with the left clamping body, and the bottom middle end of the left clamping body is penetrated by the rotating rod, and the surface of the rotating rod is penetrated by the right clamping body, and the inner surface of the right clamping body is provided with a right clamping groove. The new bottle opener is provided with a left clamping body and a right clamping body that are automatically engaged. Under the influence of the elastic force of the return spring, when the syringe bottle cap needs to be opened, the left clamping body and the right clamping body are squeezed toward the syringe bottle cap, and the right clamping body is forced to rotate outward. At this time, the syringe bottle cap is automatically engaged with the left clamping groove and the right clamping groove, achieving the effect of automatic engagement when contacting the syringe bottle cap, avoiding the trouble of the nurse needing to align the delicate operation when opening the syringe bottle cap, optimizing the steps of opening the bottle cap, improving the practicality of the device, and making the device more widely applicable.

[0004] Regarding the above-mentioned related technologies, when opening the bottle cap, the left clamp and the right clamp clamp the bottle cap by gripping the handle, and the bottle opener is lifted to open the bottle cap. The bottle opener needs to manually fix the bottle body during the opening process, which is inconvenient to operate. Utility Model Content

[0034] The present application is further described in detail below in conjunction with all the accompanying drawings.

[0035] The embodiment of the present application discloses a vial opener.

[0036] Example 1

[0037] Reference Figure 1 and Figure 2 A syringe bottle opener includes a lever 4, two support plates 1 and two clamping arms 2. The clamping arms 2 are located at the lower end of the support plates 1, and the clamping arms 2 correspond to the support plates 1 one by one. The clamping arm 2 includes a connecting rod 21 and a clamping body 22. The connecting rod 21 is fixedly connected to the lower end of the corresponding support plate 1. The clamping body 22 is slidably connected to the end of the connecting rod 21 away from the support plate 1. The support plate 1 limits the clamping body 22 through the connecting rod 21. The clamping body 22 is provided with an arc groove adapted to the syringe bottle. The arc grooves of the two clamping bodies 22 are opposite. The clamping bodies 22 can slide in the direction of approaching or moving away from each other, and a rubber gasket is embedded in the clamping body 22. Hooks 223 are fixed on both sides of the clamping body 22 along the length direction. A spring 221 is provided between the clamping bodies 22. Hanging interfaces 222 are fixed at both ends of the spring 221. The hanging interfaces 222 at both ends of the spring 221 pass through the hooks 223 for stretching the spring 221, thereby driving the two clamping bodies 22 to approach each other and clamp the syringe bottle.

[0038] Reference Figure 1 , both support plates 1 are opened with a through hole 112, and a handle 3 is provided on the inner side of the two support plates 1. The lower end of the handle 3 is fixed with a cylindrical block 31 adapted to the through hole 112. The cylindrical block 31 passes through the through hole 112 and is rotatably connected to the support plate 1. The lever 4 is located on the inner side of the two support plates 1, and the lever 4 includes a gripping rod 41. One end of the gripping rod 41 is fixed with a clamping portion 43 adapted to the bottle cap. The upper end of the gripping rod 41 is vertically hinged to the handle 3. The lever 4 is opened with a through opening 42, and a moving rod 6 adapted to the through opening 42 is provided on the inner side of the support plate 1. The moving rod 6 passes through the through opening 42. A first groove 111 is opened on the inner side of the two support plates 1. The width of the first groove 111 is adapted to the moving rod 6.

[0039] Reference Figure 3 The clamping portion 43 includes a positioning block 434, a first rectangular plate 431, a second rectangular plate 432 and a hook 433. The positioning block 434 is fixedly connected to the lower end of the holding rod 41.

The upper end of the hook 433 is fixedly connected to the lower end of the second rectangular plate 432, and the upper end of the hook 433 extends toward the direction close to the support plate 1.

[0040] When opening the bottle cap, by rotating the handle 3, the cylindrical block 31 rotates in the through hole 112, and the handle 3 drives the gripping rod 41 to move. Since the first groove 111 guides the moving rod 6, the moving rod 6 slides upward along the first groove 111, thereby driving the clamping portion 43 to move upward, and the curved hook 433 fits against the side of the bottle cap to open the bottle cap.

[0041] Example 2

[0042] Reference Figure 3 The positioning block 434 includes an extension plate 435 and a telescopic plate 436. The telescopic plate 436 is arranged at an angle. The upper end of the telescopic plate 436 is connected to the connection point between the holding rod 41 and the clamping portion 43. The extension plate 435 is fixed to the lower end of the telescopic plate 436. The extension plate 435 is placed parallel to the connecting rod 21. The telescopic plate 436 can be adjusted according to the bottle caps of different specifications of the syringe bottles so that the extension plate 435 fits the bottle caps.

[0043] Reference Figure 4 and Figure 5 The support plate 1 includes an extension plate 12 and a sleeve plate 11. The sleeve plate 11 is adapted to the extension plate 12, and both the sleeve plate 11 and the extension plate 12 are made of elastic material. The extension plate 12 is fixed with a plurality of protrusions 121 along the long side direction, and a plurality of second grooves 113 adapted to the protrusions 121 are opened on the inner side of the sleeve plate 11.

[0044] Reference Figure 6 , the same telescopic rod 5 is vertically arranged between the two support plates 1, the telescopic rod 5 includes a threaded rod 51, a first cylinder 52 and a round rod 53, one end of the round rod 53 is rotatably connected to the first cylinder 52, the round rod 53 is fixedly connected to the support plate 1 away from the first cylinder 52, one end of the threaded rod 51 is rotatably connected to the first cylinder 52, and the threaded rod 51 is threadedly connected to the support plate 1 away from the first cylinder 52, the moving rod 6 includes a first cylindrical rod 63, a second cylinder 62 and a second cylindrical rod 61, the first cylindrical rod 63 is fixedly connected to the second cylinder 62, one end of the first cylindrical rod 63 away from the second cylinder 62 is slidably connected to the first groove 111, the second cylindrical rod 61 is slidably connected to the second cylinder 62, and one end of the first cylindrical rod 63 away from the second cylinder 62 is slidably connected to the first groove 111.

[0045] When opening the caps of syringe bottles of other specifications, the extension plate 12 can slide vertically in the sleeve plate 11, and the second groove 113 and the protrusion 121 cooperate to position the extension plate 12 to adapt to syringe bottles of different heights. The telescopic plate 436 is telescopic to make the extension plate 435 fit with the upper end surface of the bottle cap to adapt to bottle caps of different heights. The first cylinder 52 rotates to make the threaded rod 51 enter the interior of the first cylinder 52, and the threaded rod 51 drives the support plate 1 to approach the first cylinder 52. The threaded rod 51 cooperates with the first cylinder 52 to provide clamping force to clamp and position the syringe bottle. When the two support plates 1 approach each other, the second cylindrical rod 61 can move to the interior of the second cylinder 62 to adapt to syringe bottles and syringe bottle caps of different specifications.

[0046] The operating principle of the vial opener of the present embodiment is as follows: when opening a vial, the vial is placed inside the two clamps 22. The clamps 22 are brought closer together by a spring 221, clamping the vial in place. By rotating the handle 3, the cylindrical block 31 rotates within the through hole 112, which drives the gripping rod 41 to move. Because the first groove 111 guides the movable rod 6, the movable rod 6 slides upward along the first groove 111, thereby driving the engaging portion 43 upward. The hook 433 engages and moves with the side of the bottle cap, opening the bottle cap.

[0047] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
